PLANlNG-MACHINE,

SPECIFICATION forming part of Letters Patent No. 331,606, dated December 1, 1885. Application filed September 4, 1885. Serial No. 176,210. (No model.)

To all whom it may concern.-

Be it known that I, F. SAMUEL BELTER, a citizen of the United States, residing at Burlington, in the county of Ohittenden and State of Vermont, have invented certain new and useful Improvements in Planing and Smoothing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in planing and smoothing machines; and it consists in the combination of the planing-iron, which is secured ina block provided with a suitable projection,an operatingroller which has a groove formed in its surface and in which the projection catches, whereby as the roller is made to revolve the block is given a reciprocating movement, as will be more fully described hereinafter.

The object of my invention is to impart to the planing iron or cutter an endwise-reciproeating motion, so that a newsurface of the cutter is constantly presented to the wood, and the surface of the wood is planed off smoothly and easily without any danger of breaking the grain of the wood, as is the case where the planer remains stationary.

Figures 1 and 2 are vertical sections, taken at right angles to each other, of a machine embodying my invention.

A represents the framework of a planingmachine; B, the rollers, such as are generally used for feeding the lumber through while it is being planed; and O,the spring which regulates the pressure of the rolls upon the lumber as it passes through the machine. These parts may either be of the construction here shown or any other that may be preferred.

The planing iron or knife is secured in the endwise-moving block I, which moves horizontally through the frame, and which block is provided with a stud or projection, J, for catching in the groove 0, which is formed in the surface of the roller 1?. As this roller -P is made to revolve by means of abelt or other driving-power, the groove in its surface imparts to the block I a constant reciprocating motion for the purpose of bringing a new part of the planing iron or cutter in contact with the wood that is being planed.

As this planing-iron is constantly moving endwise and a new surface is being constantly presented to the wood, the iron has no chance to heat, all parts are worn alike, and the grain of the wood is not liable to be injured, as is the case where the planing-iron remains stationary in the usual manner.

'The planing-iron, being made to wear uniformly by reason of its endwise movement, will keep a keen edge longer,and so perform a greater amount of work without sharpening, than where one part of the knife is always in contact with the wood.

The work done by a planing-iron which has an endwise-reciprocating motion is very perfect, as the surface of the wood is left absolutely smooth, and is therefore adapted especially for fine work.

Having thus described my invention, I claim- The combination of the frame A, suitable rollers, B, and springs which are applied to the rollers, with an endwise-moving block carrying the planing iron or knife, and which is provided with a suitable projection, and the roller 1?, having a groove formed in its surface, and in which the projection of the sliding block is made to catch, substantially as shown and described. I

In testimony whereof I affix my signature in presence of two witnesses.

F. SAMUEL BELTER.
